摘要
畜禽养殖场被认为是空气环境中生物气溶胶的重要来源。本研究对北京地区22个畜禽养殖场细颗粒物负载细菌、四环素耐药菌和红霉素耐药菌气溶胶的浓度进行检测,并对其所占丰度进行分析。结果表明,所调查的四种养殖动物中,猪舍内细颗粒物负载细菌气溶胶的平均浓度最高,牛舍内最低,分别为1.38×10~4CFU·m~(-3)和3.18×10~3CFU·m~(-3)。蛋鸡舍内细颗粒物负载细菌气溶胶的平均浓度高于肉鸡,但负载抗生素耐药菌气溶胶的平均浓度低于肉鸡。蛋鸡和肉鸡舍内空气中细颗粒物负载四环素和红霉素耐药菌所占丰度分别为7.43%,47.42%和32.53%,58.16%。本研究结果将为评价养殖场生物气溶胶对周边空气环境污染及人类健康造成的危害提供基础数据。
